SITUATION 9 Consider the fallowing population for the diameter of 36 rivet heads (in 1/100 of an inch) of ane kind in a production line, labeled in arder as rivet 1, rivet 2, and so on, as follows (in order): 6.72 6.77 6.82 6.70 6.78 6.70 6.62 6.75 6.66 6.66 6.64 6.76 6.73 6.80 6.72 6.76 6.76 6.68 6.66 6.62 6.72 6.76 6.70 6.78 6.76 6.67 6.70 6.72 6.74 6.81 6.79 6.78 6.66 6.76 6.76 6.72 Five samples of rivet heads are to be picked in order to estimate the mean diameter among the entire population. (a) Construct a sampling distribution of sample mean for the following five-sample combinations: 1-3-5-7-9, 2-4-6-8-10, 11-13- 15-17-19, 12-14-16-18-20, 21-23-25-27-29, 22-24-26-28-30, 31- 33-35-1-3, 32-34-36-2-4, 5-7-9-11-13, and 6-8-10-12-14. (b) Determine the population mean diameter. Which of the five- sample combinations from (a) has its sample mean closest to the population mean?
